Title: Permissioned Distributed Ledgers for Land Transactions
Authors: Fernando, D. T.
Issue Date: 22-Jul-2021
Abstract: Considering the inefficiency and ineffectiveness of the current manual land registration systems being practiced in Sri Lanka and the emergence of the concept of blockchain based land registries as a successful replacement for badly kept, mismanaged and/or corrupt land registries from around the world, this research proposes a permissioned distributed land ledger solution for Sri Lanka. The proposed solution is an island wide unified land ledger which addresses unequal regional land transaction density conditions across the island, as opposed to the present regional ledger system. The final solution presents optimal content for the ledger (extracted from the current folio), has reassigned duties to state validators and has got away with the folio system while ensuring derivation of the pedigree/ folio tree for a land at a given time. The proposed solution was implemented using Hyperledger Fabric v1.2. It was evaluated for performance on an AWS t2.large instance with 2 vCPUs, 8GiB memory, against the implementation of a regional distributed land ledger, under different land transaction density conditions and failure conditions. The proposed solution records higher throughput, lower latency and tolerance for fail-stop conditions than the regional distributed land ledger. Further, the proposed solution does not show a significant drop of throughput up to two crash failures in production scale deployment.
